RICHARD B. DALY, OF VOONSOCKET, RHODE ISLAND, ASSIGNOR TO THE VOONSOCKET MACHINE AND PRESS COMPANY, OF SAME PLACE.

ROVlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 581,573, dated April 27', 1897.

Application filed September I9, 1895. Serial No. 562,956. (No model.)

To all whom t may concern:

Be it known that I, RICHARD DALY, of lVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Roving-liachines, of which the following is a specification.

This invention relates to an improvement in roving or similar machines; and it consists in the novel features of construction and relative arrangement of parts hereinafter fully described in the specilication, clearly illustrated in the drawings, and particularly pointed out in the claims.

Reference is to be had to the accompanying two sheets of drawings, forming a part of this application, in which like characters indicate like parts wherever they occur.

In the drawings, Figure l represents a front elevation of a portion of a roving or similar machine constructed in accordance with my invention. Fig. 2 is a detailed view showing the construction and arrangement of parts by which the flier and bobbin are rotated and the bobbin raised and lowered. Fig. 3 represents a cross-sectional view on the line 3 3 of Fig. 2. Fig. 4 represents a longitudinal sec tion of the bolster and its associated parts.

Prior to my invention in machines of this kind it has been the practice to give a vertical movement to the gearing and shafting by which the bobbins were rotated. This construction is objectionable for many reasons. The shafting having a vertical movement, it is necessary to strengthen the machine-frame for this particular purpose, and, more than that, it is necessary to make the machine heavy at the base to compensate in the change in the center of gravity with the up-and-down movement of the shafting and gearing referred to. By my invention these objections are overcome. XVhile the bobbin has an upand-down as well as rotary movement, as before, the shafting and gearing that rotates the bobbins are fixed against all movement except that of rotation. Thus the power heretofore used for raising the bobbin with its connected shafting and gearing may be greatly diminished, since it is only necessary to carry up the auxiliary bolster-rail and the bobbins, the shafting not being raised Vand lowered, as in other machines. Moreover, I am enabled to place the shafting near the base of the machine, thereby greatly adding to its stability, and by this arrangement I am enabled to do away with considerable gearing between the main shaft and the gears that drive the bobbin.

Referring to the drawings, a represents the framework of the machine, divided, as usual, into sections or samsons, thevpower being applied, as usual, to the gearing located` on the first samson. The framework or samson is provided with suitable base portions or supports a', provided with lugs d2, in which are mounted set-screws A rail Z2, having a base portion b' and an upper extending portion b2, rests upon the base portions a and between the lugs a2, and is held in place by the set-screws a3. To this rail, by means of suitable bolts c', are secured the bearings c for the shafts c?, upon which the gears c3 are mounted and fixed thereon by means of setscrews c4, these gears driving the spindle, as shown. There are two shafts c2 and two rows of the spindles, although a greater or less number of rows could be used.

Formed integral with the framework of each bearing there is a step c5, apertured, as at c, to receive the end of the spindle c7 and act as a support therefor. This step may be provided with an oil-reservoir o8, if desired.

c10 represents arms integral with the framework of the bearing c, that extend laterally outward from the rail l). At their extremities these arms are grooved, as at c, to receive a cover or casing cl2, that incloses the gearing driving the spindles and bobbins.

c represents a beveled gear secured to the lower end of the spindle by a set-screw cl3, this gear meshing with the gear c3 on the shaft c2, the rotation of the shaft c2 thus conveying motion to the spindle and to its iiier G14. The shaft or shafts c2, where more than one are employed,are driven by means of gears clfast on the ends of said shafts on the outside of the first samson. These gears C15 are in mesh with each other, as shown in Fig. 2, one being in mesh with an idle or intermediate gear o16, that in turn is driven by a gear el?, fast on the main shaft cls.

IOO

d represents the bolster-rail, suitably secured to several sections or samsons of the framework of the machine. CZ represents arms secured to this rail by bolts b2. These arms are arranged on either side of said rail, as shown, and are provided at their free ends with vertically-arran ged hu bs c3, suitably apertured to receive and act as bearings and supports for the quill that drives the bobbins, and necessarily also for the spindle that is arranged within the quills.

The rail (Z is stationary and not required to be as heavy as in other machines, since it only carries the bearings for the quills.

(Z5 represents what I term a supplemental bolster rail, arranged above the main bol ster-rail CZ and outside of the casing and gearing, the bolster-rail (Z being arranged inside of said casing.

The supplemental bolster-rail Z5 is mounted upon the free ends of arms CZ, that are connected to vertical racks CZ7, suitably mounted for a vertical movement and arranged to slide in suitable bearings d70 on the sides of the samsons. These racks are driven by pinions CZS, fast on the shafts d, the latter being driven through the medium of the cone-pullower end of the quill, preferably, does not ley mechanism, that is Common.

d10 represents plates secured by bolts CZ1l to the top of A the supplemental bolster rail. These plates extend on either side of the supplemental bolster-rail, and at their free ends are suitably apertured, as at CP2, to receive and act as a support for the bolsters (Z13, the

latter being free to turn in their supports and provided with the usual liange CZ, having a pin CZ15 to engage the slots d1 on the bottom of the bobbin CZ.

The supplemental bolster -rail serves to raise and lower the bobbin by means of the bolster, thus obviating the necessity of raising shaft by which the bolster and bobbin are rotated.

f represents shafts eorrespondin g in number to the row or rows of spindles, one shaft being used where there is one row. 0n these shafts are rigidly mounted skew-gears j" by means of set-screws f2. These gears engage beveled gears f3, rigidly mounted upon the lower end of the quills f4, the said quills being hollow and arranged upon the spindles c7. These gears f3 at their lower end rest upon collars f5, rigidly mounted upon the spindles by means of set-screws. (Not shown.) Thus the quills and gears f3, to which the quills are rigidly connected, are supported by these collars, the gears being free to turn on said collars. These collars are provided with an upwardly-extending hub portion 01 flange f, that is arranged in the hub portion of the gears. The hub portion f7 of the gears f3 extend above and below the teeth of the gears, as shown, the lower portion of this hub surrounding the hub of the collar f5, as already stated, and the upper portion of the hub surrounding and engaging the lower end of the quill, to which it is rigidly attached. The

quite touch the hub of the eollarsf. The quill is chambered, as at flo, for a portion of its length, the upper portion of the quill not being chambered and fashioned to rotatably fit the spindle and form a bearing between said quill and spindle, as atfu. Thus two bearin g-poi nts are provided for the gears and their attached quills-to wit, at fu between the spindle and quill and at the opposite ends of said quills by the hubs of the collars f5 and gears f3.

(Zw represents a spline or feather secured in any desired way on the inside of the bolster (Z13 and arranged to slide in the groove fm in the quill. By this means provision is made for the rotation and the vertical movement of the bobbin.

f13 represents gears fast upon the shafts f 85 and meshing with each other, whereby said shafts are driven in unison. Power is conveyed to one of these shafts by means of a spur-gear f, mounted upon the short shaft j, this gear meshing with the pinion f1, fast upon one of the shaftsf, this pinion being shown in dotted lines in Fig. 2.

The power from the main shaft is communicated to the gear ft' as follows: The main shaft als at its end inside of the second samson is provided with a spur-gear 7L, that mesh es with an intermediate gear h', mounted upon a short shaft or stud 7b2, the gear 7L in turn meshing with the sp ur-gear h3, fast upon the shaft h4, upon which is rigidly mounted a cone-pulley h5, a belt hconnectingthis pulley with a similar pulley 7L?, fast upon a shaft hs, said cone-pulley shafts being suitably mounted in the framework of the machine. One end ofthis cone-pulley shaft hs is provided with a pinion hg, that meshes with a spur-gear h1", forming a part of any preferred differential motion 72,11 used in this class of machines. From thence the power is transmitted, by means of a sleeve k12, loosely mounted upon the shaft cls, provided with a spur-gear 7tlg, that meshes with the gear f, to the shaft f.

Thus it will be seen that the power driving the spindles is transmitted from the main shaft 018 by means of the shafts f and the intermediate gearing and that the power for operating the supplemental bolster-rail and also the bobbins is transmitted from the main shaft by means of the cone-pulleys and the differential motion. The spindles c7 and their fliers are driven by the shafts c2 and their connected gearing, while the quills are rotated through the medium of the shafts f, located directly above the shafts c2, the bobbins being raised and lowered by means of the racks connected to the supplemental bolster-rail that carries the plates in which are mounted the bolsters Z113.

From the foregoing it will be seen that I have invented an exceedingly efficient and simple machine. The power necessary for driving the machine is greatly lessened and the stability and eflicicncy of the machine enhanced. The various shafts and gears be- IOO IIO

ing located at the bottom of the machine increases its stability, greatly reduces its cost of construction, and greatly increases its durability.

Attention is particularly called to the manner of connecting the differential motion with the shafts that drive the quills. These shafts being stationary, I am enabled to dispense with the pivoted shaft heretofore used with its many modifications, the sleeve of the differential motion being provided with a spurgear which intermeshes with an idlegear that in turn transmits the power directly to the shafts f.

I am aware of the English Patent No. 2,380, dated October 18, 1859, which discloses a quill loosely surrounding the spindle and having a bea-ring in a fixed or non-rotary portion of the framework, and I do not claim herein anything disclosed in said patent.

Having thus explained the nature of my invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all the modes of its use, what I claim, and desire to secure by Letters Patent, is-

1. In a roving or similar machine, the combination of a spindle carryingacollar, a quill loosely surrounding lsaid spindle and finding a bearing on said collar, a vertically-lnovable bolster rotatively and slidingly engaged with said quill, means for raising and lowering the bolster, means for rotating the quill, and means for rotating the spindle, arranged substantially as described.

2. In a roving or like machine, the combination of a spindle carrying a collar, formed with an enlarged lower portion constituting a rest or step, and a reduced upwardly-eX- tending portion constituting` a bearing, a quill loosely surrounding the said spindle above the collar and admitting the upper end of the same, a gear on said quill and having an elongated hub portion extending over the reduced portion of the said collar, a verticallymovable bolster rotatively and slidingly engaged with the quill, means for raising and lowering the said bolster, means for rotating the quill by engagement with the gear thereon, and means for rotating the spindle.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 14th day of September, A. D. 1895.
